and tend to throw the transfer-lever G to the left, in case no means is provided to lock said lever G against this tendency.

In order to secure the tens-transfer lever in its normal position duringthe taking of totals and subtotefls a lock-lever7 14 having a lug or projection l-l is provided, said lever .M being' fixed on an oscillatory shaft 13 so that the projection 14 can be moved into und out of engagement with recess or notch iii-the upper end of the transfer lever 6. ll'pon the shait 13 is also fixed an Aarm orlever 15, which is connected to the full lines whereby the lever G is n'evented from being swung to the left by any fiction` lfVhen the totalizother than a proper one. ing lever is inits normal position, the lever 14 is maintained in elevation so as to be free from the notch or recess 8 and the lever 6 is tree to move to any operative impulse impartial thereto.

lNhat l claim es my invention is:-

n a counting:T mechanism for computinggmachines,the combination with counting' wheels mounted forl oscillation into its addingV and subtracting' positions, means for setting up the counting Wheels, a tens-transfer lever, transfer pins carried by said counting' wheels to coperate with Vsaid transfer le-l ver, and a locking' lever to eng-.ige said trans-f fer lever when the counting mechanism is operated to tnlie a total or a sub-total.

ln testimony whereof I atlix my signature in presence of two witnesses.
